2RL-750

Overview

The Sifam Tinsley Instrumentation Inc 2RL-750 is an ANSI Metering Class current transformer designed for power monitoring applications requiring high accuracy and minimal phase angle error. It features a primary ampere rating of 75 A with a secondary output of 5 A, establishing a current ratio of 15:1. The device supports a frequency spectrum ranging from 50 Hz to 400 Hz. It utilizes a free-hanging in-line mounting configuration with a double nut design and an inner diameter of 1.05 inches.

Feature Summary

• ANSI Metering Class construction for precise power monitoring
• Free-hanging in-line installation with double nut design
• Broad-spectrum frequency support from 50 Hz to 400 Hz

Applications

• Power monitoring systems
• Industrial electrical metering
• High accuracy current sensing

Procurement Notes

Verify the specific manufacturer designation, as Sifam Tinsley instrumentation components may be sourced through various distributors or legacy supply chains. Confirm that the unit matches the exact ANSI specifications and physical dimensions required for the intended panel or busbar integration. Ensure compatibility with the target frequency range and load requirements before finalizing acquisition.

Selection Notes

Select this component when a 75 A primary rating and 15:1 transformation ratio are necessary for accurate energy measurement. The wide frequency tolerance makes it suitable for diverse industrial environments. Consider the physical mounting constraints, specifically the need for a free-hanging in-line setup with adequate clearance for the double nut assembly during installation.

Part Context

This model belongs to the Omega series of current transformers, which are engineered for robust performance in demanding electrical environments. The 2RL-750 variant specifically addresses applications where standard metering classes are insufficient, providing enhanced reliability for continuous operation in power distribution networks.
